In the vast Joker Star Cluster where four stars shine, a comet named Stant visits every millennium, carrying its own set of planets. Long ago, the powerful Farus Di Kanon Empire, now dubbed the 'Super Empire', ruled over these stars with advanced technology before its collapse in 9000 AD. After the empire's fall, civilization struggled for survival, losing much of its former knowledge. Eventually, the imperial families of Amaterasu, Fillmore, and Hathuha united to establish the Joker Calendar (JC era) in hopes of promoting unity and peace. However, peace remains a distant dream as warfare rages on in the year 2988 JC. Amidst interstellar travel and genetically engineered 'fatimas' guiding formidable mortar headds in battles, nations continue their relentless conflicts with only a faint glimmer of hope for harmony.
